Abstract

An apparatus implementable on a pistol includes a compensator and a guide rod. The guide rod has a front distal end and a rear distal end opposite the front distal end. The compensator includes a muzzle brake having a recoil-reduction device, a first through hole and a second through hole. When the compensator is implemented on the pistol: (a) the recoil-reduction device redirects propellant gases to counter a recoil force upon firing of a round of ammunition by the pistol; (b) the first through hole is aligned with a barrel of the pistol to allow firing of the round of ammunition, and (c) the second through hole receives the front distal end of the guide rod therein such that an interface between the guide rod, the muzzle brake and a slide of the pistol is keyed to prevent rotation of the guide rod.

First claim

What is claimed is:

1. An apparatus implementable on a pistol, comprising:
a guide rod receivable in a slide of the pistol, the guide rod having a front distal end and a rear distal end opposite the front distal end;
a compensator comprising a muzzle brake, the muzzle brake comprising a recoil-reduction device, a first through hole and a second through hole,
wherein, when the compensator is implemented on the pistol:
the recoil-reduction device is configured to redirect propellant gases to counter a recoil force upon firing of a round of ammunition by the pistol,
the first through hole is aligned with a barrel of the pistol to allow firing of the round of ammunition, and
the second through hole is configured to receive the front distal end of the guide rod therein such that an interface between the guide rod, the muzzle brake and a slide of the pistol is keyed to prevent rotation of the guide rod; and

a returning mechanism received in the second through hole of the muzzle brake and disposed around the front distal end of the guide rod.

2. The apparatus of claim 1 , wherein the muzzle brake comprises a front side and a rear side that is opposite the front side and facing the pistol when the compensator is implemented on the pistol, and wherein the recoil-reduction device comprises:
at least one baffle opening disposed on the muzzle brake between the front side and the rear side;
at least one porting hole disposed on the muzzle brake between the front side and the rear side; or
at least one surface for propellant gases to act upon.

3. The apparatus of claim 1 , wherein the muzzle brake comprises a front side and a rear side that is opposite the front side and facing the pistol when the compensator is implemented on the pistol, wherein the first through hole communicatively connects the front side and the second side, and wherein the first through hole comprises:
a first front opening on the front size of the muzzle brake; and
a first rear opening on the rear size of the muzzle brake, the first rear opening larger than the first front opening and configured to receive a muzzle of a barrel of the pistol when the compensator is implemented on the pistol.

4. The apparatus of claim 1 , wherein the muzzle brake comprises a front side and a rear side that is opposite the front side and facing the pistol when the compensator is implemented on the pistol, wherein the second through hole communicatively connects the front side and the second side, and wherein the second through hole comprises:
a second front opening on the front size of the muzzle brake; and
a second rear opening on the rear size of the muzzle brake, the second rear opening smaller than the second front opening and configured to receive the front distal end of the guide rod when the compensator is implemented on the pistol,
wherein a shape of the second rear opening is non-circular.

5. The apparatus of claim 1 , wherein the returning mechanism comprises a wire, a hydraulic spring, a gas spring, a hydraulic dampener, a gas dampener, a hydraulic piston, or a gas piston.

6. The apparatus of claim 1 , wherein a tip of the front distal end of the guide rod includes a flange such that the returning mechanism is compressed between the flange and an inner wall of the second through hole on the rear side of the muzzle brake upon firing of a round of ammunition by the pistol when the compensator is implemented on the pistol.

7. The apparatus of claim 1 , further comprising:
a recoil spring received in a slide of the pistol when the compensator is implemented on the pistol and disposed around the guide rod; and
a guide rod bushing received in the slide of the pistol when the compensator is implemented on the pistol and disposed around the guide rod,
wherein a tip of the rear distal end of the guide rod includes a flange such that the recoil spring is compressed between the flange and an inner wall of the slide upon firing of a round of ammunition by the pistol,
wherein a cross-sectional profile of an opening of the guide rod bushing is non-circular, and
wherein the guide rod bushing includes a lug shaped to mate with a bottom surface of the barrel to prevent rotation of the guide rod.

8. An apparatus implementable on a pistol, comprising:
a compensator comprising a muzzle brake having a front side and a rear side that is opposite the front side and facing the pistol when the compensator is implemented on the pistol, the muzzle brake comprising:
a recoil-reduction device configured to redirect propellant gases to counter a recoil force upon firing of a round of ammunition by the pistol;
a first through hole communicatively connecting the front side and the second side, the first through hole comprising:
a first front opening on the front size of the muzzle brake; and
a first rear opening on the rear size of the muzzle brake, the first rear opening larger than the first front opening and configured to receive a muzzle of a barrel of the pistol when the compensator is implemented on the pistol; and

a second through hole communicatively connecting the front side and the second side, the second through hole comprising:
a second front opening on the front size of the muzzle brake; and
a second rear opening on the rear size of the muzzle brake, the second rear opening smaller than the second front opening and configured to receive a front distal end of a guide rod of the pistol when the compensator is implemented on the pistol,

wherein a shape of the second rear opening is non-circular.

9. The apparatus of claim 8 , wherein the recoil-reduction device comprises:
at least one baffle opening disposed on the muzzle brake between the front side and the rear side;
at least one porting hole disposed on the muzzle brake between the front side and the rear side; or
at least one surface for propellant gases to act upon.

10. The apparatus of claim 8 , further comprising:
a guide rod having a front distal end and a rear distal end opposite the front distal end, a cross-sectional profile of the guide rod being non-circular,
wherein, when the compensator is implemented on the pistol, the front distal end of the guide rod is received in the second through hole of the muzzle brake.

11. The apparatus of claim 10 , further comprising:
a returning mechanism received in the second through hole of the muzzle brake and disposed around the front distal end of the guide rod.

12. The apparatus of claim 11 , wherein the returning mechanism comprises a wire, a hydraulic spring, a gas spring, a hydraulic dampener, a gas dampener, a hydraulic piston, or a gas piston.

13. The apparatus of claim 11 , wherein a tip of the front distal end of the guide rod includes a flange such that the returning mechanism is compressed between the flange and an inner wall of the second through hole on the rear side of the muzzle brake upon firing of a round of ammunition by the pistol when the compensator is implemented on the pistol.

14. The apparatus of claim 10 , further comprising:
a recoil spring received in a slide of the pistol when the compensator is implemented on the pistol and disposed around the guide rod; and
a guide rod bushing received in the slide of the pistol when the compensator is implemented on the pistol and disposed around the guide rod,
wherein a tip of the rear distal end of the guide rod includes a flange such that the recoil spring is compressed between the flange and an inner wall of the slide upon firing of a round of ammunition by the pistol,
wherein a cross-sectional profile of an opening of the guide rod bushing is non-circular, and
wherein the guide rod
